City Tycoon is a popular system introduced in NTE's CBT3, integrating multiple city life simulation elements. Players can: 1) Purchase real estate in different Hethereau City locations; 2) Drive various vehicles through the city; 3) Build deeper relationships with characters through social interactions; 4) Enjoy mini-games including mahjong, racing, and more (launch version adds AI opponents). This system gives NTE rich casual gameplay beyond combat and exploration, making it one of the game's standout features.
